Add more tests of strtod end pointer
Although there are some tests in tst-strtod2 and tst-strtod3 for the end pointer provided by strtod when it doesn't parse the whole string, they aren't very thorough. Add tests of more such cases to tst-strtod2. Tested for x86_64. (cherry picked from commit b5d3737b305525315e0c7c93ca49eadc868eabd5)
